By reducing the operating pressure, the centrifugal force is also reduced.
At the same time the vibration amplitude remains almost constant.
Filling mist Fill the lubricator body with approx. 60 ml of oil corresponding to the per-
lubricator missible operating conditions (see page 7; "Lubrication").
Notice: The NVV is ready for operation only after filling and correct func-
tioning of the mist lubricator.
Initial Before initial start-up, also pour 4-6 drops of oil onto the sieve of the claw
lubrication coupling of the NVV.
